degraded performance in the WLAN nehvork and also possibly
interfere with the radar's ability to detect weak echoes.
It will be shown in this paper how the WLAN nehvork can be
accurately modeled and simulated. Its simulated performance
will then pared wim measured results to verify the
accuracy of the simulation model. Once this is done the radar
signal can be applied to the work either by simulated
signal sources, measured signal data or bination of these.
The eNects on the WLAN performance can be quickly
evaluated for a large number of conditions such as frequency,
power level, hopping parameters, etc. The standard
